The input of heat into an inherently endergonic reaction, such as the elimination of cyclohexanol to cyclohexene, can be seen as coupling an unfavourable reaction ( elimination ) to a favourable one ( burning of coal or other provision of heat ) such that the total entropy change of the universe is greater than or equal to zero, making the " total"

The chemical structure of venlafaxine is designated ( R / S )-1-[ 2-( dimethylamino )-1-( 4 methoxyphenyl ) ethyl ] cyclohexanol hydrochloride or ( ?)-1-[ a [ a-( dimethylamino ) methyl ] p-methoxybenzyl ] cyclohexanol hydrochloride, and it has the empirical formula of C 17 H 27 NO 2.

Other esteramides are derived, e . g . from 2-methylglutaronitrile which, after alkaline hydrolysis, is converted into 2-methylglutaric acid, cylized with acetic anhydride to give 2-methylglutaric anhydride, reacted with dimethylamine to form the monoamide, reacted to a acid chloride with thionyl chloride and formed to an ester with more hydrophobic alcohols ( like butanols or cyclohexanol ).
